❗At each aid station, this is the amount of carbs and water you should have ingested ❗
🤓 Enduraw advices:
- 🚩 Do not try new nutrition on race day! Make sure you eat food you know and trained with 🏃➡️
- To counterbalance sweating, make sure you have isotonic drinks or salty food during your effort 🧂
- Alternate between hot and cold food ☕🧋
- Chose different carbs inputs to keep taste and motivation 🥨🍫🍑
- Performance also stand in your pleasure! Add pleasure aliments, and not only carbs if needed 🧀🥚
👑 - More features
📈 For greater accuracy, your nutrition can be even more personalized with your exact intake per hour.
This can be determined by experience (what you're used to, what worked well for you in the past) or by carrying out laboratory tests.
🏆 To achieve your greatest goals, pacing plans can be optimized with regard to your physiological response to the effort (heart rate, energetic output).
